[0047] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0048] The embodiment of the present application provides an automatic joint tightening device, including a fixing mechanism 1, a clamping mechanism 4, a moving mechanism 6 and a screwing mechanism 5, please refer to Figure 1 .

[0049] The fixing mechanism 1 is used to fix the component 2, which needs to wait for the connector 3 to be installed. Here, the component 2 and the fixing mechanism 1 are detachably connected. After the connector 3 of a component 2 is installed, the component 2 can be removed and wait for subsequent use. The specific detachable connection method can be a snap connection, a fastener 14 connection, etc., which can facilitate installation and removal while ensuring reliable and stable fixation.

[0050] The device 2 on which the connector 3 is to be installed may be in the form of a pipeline, a water collector, etc., and may be any device 2 on which the connector 3 is to be installed.

[0051] The fixing mechanism 1 is specifically applicable to the setting of different types of devices 2 based on the detachable connection between the fixing mechanism 1 and the device 2. Even for different types of devices 2, as long as the device 2 and the fixing mechanism 1 can be fastened by the fastener 14, it will suffice.

[0052] The clamping mechanism 4 is provided with a plurality of clamping cavities 41 arranged along the moving route of the fixing mechanism 1. The clamping cavities 41 can clamp the fixing mechanism 1, that is, can relatively fix the fixing mechanism 1 so as to relatively fix the device 2 on the fixing mechanism 1.

[0053] The mobile mechanism 6 is connected to the fixed mechanism 1, and the fixed mechanism 1 can be driven to move by the mobile mechanism 6. The mobile mechanism 6 can specifically be made of a cylinder, oil cylinder, electric cylinder, gear rack assembly and motor, linear module, robotic arm, etc. that can realize linear motion, and can be flexibly set according to actual movement requirements.

[0054] The fixing mechanism 1 can be moved out of any clamping cavity 41 and into an adjacent clamping cavity 41. That is, the fixing mechanism 1 can move in two directions: one direction relative to the clamping cavity 41, and the other direction corresponding to movement along two adjacent clamping cavities 41. Accordingly, the moving mechanism 6 can also provide at least two directions of drive to meet usage requirements.

[0055] The screwing mechanism 5 is arranged on the moving route of the fixing mechanism 1, so that the movement of the fixing mechanism 1 can deliver the device 2 and the joint 3 to the working position of the screwing mechanism 5. By further moving the screwing mechanism 5 and approaching the joint 3, a joint 3 delivered by the fixing mechanism 1 can be tightened on the device 2, and then the screwing mechanism 5 removes contact with this joint 3; the moving mechanism 6 moves the fixing mechanism 1 from the state where the previous joint 3 is clamped in the clamping cavity 41 to another clamping cavity 41, so that the next joint 3 can reach the working position, and by moving the screwing mechanism 5 and approaching the joint 3 again, the next joint 3 can be tightened to the device 2, and this is repeated until all the joints 3 on the device 2 are screwed.

[0056] In this embodiment, it should be noted that the connector 3 can be pre-installed on the device 2. This installation does not necessarily mean a secure installation, but rather serves to hold the connector 3 on the device 2 to prevent it from falling, thereby facilitating subsequent tightening operations. For example, the connector 3 can be installed on the device 2 by manually tightening it several times, and then tightened one by one using the tightening mechanism 5.

[0057] In this embodiment, the screwing mechanism 5 can move toward or away from the joint 3, and can also rotate to tighten the joint 3. After tightening the joint 3, the joint 3 and the screwing mechanism 5 can be relatively separated by simply moving the screwing mechanism 5 away from the joint 3.

[0058] In this embodiment, the clamping cavity 41 can be a closed cavity or a cavity with an opening. Specifically, when the clamping cavity 41 is a closed cavity, such as a circular cavity, the movable mechanism 6 can drive the fixing mechanism 1 to move to extend or retract. The extension here corresponds to the situation where the fixing mechanism 1 is relatively fixed in the clamping cavity 41, and the retraction corresponds to the situation where the fixing mechanism 1 is relatively moved out of the clamping cavity 41 and can move to the next clamping cavity 41. When the clamping cavity 41 is a cavity with an opening, such as a U-shaped cavity, the movable mechanism 6 can drive the fixing mechanism 1 to move to detach from the clamping cavity 41 from the opening or enter the clamping cavity 41 from the opening. The detachment from the clamping cavity 41 here corresponds to the situation where the fixing mechanism 1 can move to the next clamping cavity 41, and the entry from the opening into the clamping cavity 41 here corresponds to the situation where the fixing mechanism 1 moves to be relatively fixed in the clamping cavity 41.

[0059] In this embodiment, since the tightening of several joints 3 on the device 2 relies on the moving transportation of the moving mechanism 6 and the automated unified tightening of the screwing mechanism 5, it can ensure better tightening reliability, save time and effort, and improve the efficiency of the installation of the joints 3.

[0060] Based on the above examples, please refer to Figure 1 、 Figure 3 The clamping cavity 41 includes a clamping section 411 and a disengagement section 412 connected thereto. The disengagement section 412 extends in a direction away from the clamping section 411 to guide the fixing mechanism 1 to move into or out of the clamping section 411 .

[0061] In this embodiment, the clamping section 411 is the part that can reliably clamp the fixing mechanism 1, and can relatively fix the fixing mechanism 1 in the clamping mechanism 4 to wait for the subsequent screwing operation of the joint 3; the disengagement section 412 is used to guide the fixing mechanism 1 to enter or move out of the clamping section 411, and can ensure the smooth transfer of the fixing mechanism 1 between adjacent clamping cavities 41, and ensure the reliable tightening of several joints 3 on the device 2.

[0062] In this embodiment, the guidance of the disengagement section 412 can facilitate the movement in and out of the fixing mechanism 1, avoiding damage to components or the clamping cavity 41, wherein the disengagement section 412 can be specifically set as an inclined surface guide or an arc surface guide, which can provide a reliable guiding effect.

[0063] Furthermore, the side of the inclined or curved guide away from the clamping section 411 may have an opening or may be closed. For example, the side of the inclined or curved guide away from the clamping section 411 may have an opening. This opening enables the portion of the fixing mechanism 1 corresponding to the clamping cavity 41 to smoothly enter the clamping section 411 along the inclined or curved guide, and also enables the fixing mechanism 1 to smoothly move out of the clamping cavity 41 through this opening.

[0064] If the inclined guide or arc guide is closed on one side away from the clamping section 411, the fixing mechanism 1 can be separated from the disengagement section 412 before reaching the closed position. The fixing mechanism 1 does not enter the clamping section 411 from the closed position of the disengagement section 412, so it is not restricted by the closed section of the disengagement section 412. In this case, the overall structural strength and hardness of the clamping cavity 41 can be guaranteed.

[0065] In this embodiment, the disengagement section 412 extends in a direction gradually away from the clamping section 411. It should be noted here that the extension direction can also be regarded as a direction away from the device 2. The clamping section 411 is relatively close to the device 2, and the disengagement section 412 is relatively far away from the device 2, so that the disengagement section 412 can provide reliable guidance for the device 2 to move in and out without affecting the movement process of the device 2 with the moving mechanism 6.

[0066] Based on any of the above embodiments, please refer to Figure 3 The disengagement section 412 is tilted relative to the clamping section 411 , and an opening is provided on a side of the disengagement section 412 away from the clamping section 411 .

[0067] like Figure 3 As shown, the disengagement section 412 is formed by a slanted plate bent relative to the clamping section 411. The slanted plate can be formed by bending or connected to the disengagement section 412 by welding, and has certain structural strength and hardness.

[0068] The clamping cavity 41 formed by the disengagement section 412 and the clamping section 411 can facilitate the movement of the fixing mechanism 1 into any clamping cavity 41, and can facilitate the smooth disengagement of the fixing mechanism 1 from any clamping cavity 41, so as to meet the requirements of sending several connectors 3 of the device 2 to the working position of the screwing mechanism 5 through the movement of the fixing mechanism 1, so that they can be screwed one by one, so that the screwing of the connectors 3 on the device 2 is automated, thereby improving the efficiency and reliability of the installation of the connectors 3.

[0069] by Figure 1 For example, when the fixing mechanism 1 is disengaged from the clamping cavity 41, it moves from bottom to top, so that the fixing mechanism 1 as a whole is higher than the surface of the disengagement section 412, so that the driving force from left to right can drive the fixing mechanism 1 to move to the top of the adjacent clamping cavity 41, and then the fixing mechanism 1 moves from top to bottom, so that the fixing mechanism 1 is relatively fixed in the clamping section 411 of the adjacent clamping cavity 41.

[0070] Based on any of the above embodiments, please refer to Figure 3 The clamping mechanism 4 includes at least two side plates 42 disposed opposite to each other, with a movable space 43 formed between any two adjacent side plates 42. The fixing mechanism 1 can move within the movable space 43. The side plates 42 have a certain thickness, good structural strength, and certain anti-impact and anti-deformation properties, thereby ensuring reliable operating performance.

[0071] The moving space 43 between any adjacent side panels 42 can be used as a space for the fixing mechanism 1 to move in different directions, and the fixing mechanism 1 is restricted to move within the moving space 43 to perform a certain position limitation.

[0072] Each side plate 42 is provided with a clamping cavity 41. Clamping cavities 41 located in the same position on at least two side plates 42 can work together to clamp the fixing mechanism 1. The same position is perpendicular to the direction of movement of the fixing mechanism 1 relative to the same clamping cavity 41. The provision of multiple clamping cavities 41 ensures reliable clamping of the fixing mechanism 1, ensuring reliable stability when the fixing mechanism 1 delivers the component 2 to the working position of the screwing mechanism 5, and ensuring reliable screwing of the connector 3.

[0073] In this embodiment, by providing at least two side panels 42, the number of side panels 42 can be increased or decreased based on actual circumstances to meet different usage requirements. If the overall size of the device 2 is large and extra side panels 42 would interfere, the excess can be removed. If the portion of the fixing mechanism 1 corresponding to the clamping cavity 41 is large and requires the coordinated action of multiple clamping cavities 41 for reliable clamping, the number of side panels 42 can be increased.

[0074] like Figure 3 As shown, when two side panels 42 are provided, the separation sections 412 in both side panels 42 are provided away from the moving space 43 to maintain good symmetry and ensure structural strength.

[0075] Based on any of the above embodiments, the moving mechanism 6 includes a first moving component and a second moving component. The first moving component can drive the fixing mechanism 1 to move along the first direction, so that the fixing mechanism 1 moves into or out of the clamping cavity 41. The second moving component is connected to the first moving component to realize the movement of the fixing mechanism 1 along the second direction, so that the fixing mechanism 1 can move between two adjacent clamping cavities 41. The first direction is perpendicular to the second direction. Figure 1 For example, the first direction is the movement in the up-down direction, and the second direction is the movement in the left-right direction.

[0076] The distance that the second movable component moves in a single movement is a multiple of the distance between two adjacent clamping cavities 41, and the multiple here can be one, two or more. Among them, the types of connectors 3 on the device 2 may be consistent or inconsistent, and here it mainly refers to the difference in the outer diameter of the connector 3. For example, the distribution form of large-size connector-small-size connector-large-size connector-small-size connector, then the second movable component can first drive the large-size connector to move to the working position of the screwing mechanism 5 for screwing. In this case, the corresponding distance that the second movable component moves in a single movement is twice the distance between the adjacent clamping cavities 41. Of course, the second movable component can also drive the large-size connector to move to the working position of the screwing mechanism 5 for screwing, and then drive the small-size connector adjacent to it to move to the working position of the screwing mechanism 5 for screwing, and then screw the next large-size connector, and so on.

[0077] It should be noted that, for connectors 3 with different outer diameters, the screwing mechanism 5 can also have screwing parts of various sizes. For example, multiple sets of screwing parts can be provided, and the corresponding required size can be selected according to actual conditions.

[0078] Based on any of the above embodiments, please refer to Figure 6 、 Figure 7 The first movable assembly includes a carrier plate 66 and a fixed plate 62. One side of the carrier plate 66 is provided with a bearing surface for supporting the fixing mechanism 1. The other side of the carrier plate 66 is provided with a plurality of lifting cylinders 65. The movable ends of the lifting cylinders 65 are fixed to the carrier plate 66, and the fixed ends of the lifting cylinders 65 are connected to the fixed plate 62. The fixed plate 62 is connected to the second movable assembly. The bearing surface is the portion for placing the fixing mechanism 1 and the device 2. Positioning portions can be provided on the bearing surface to ensure the reliable stability of the fixing mechanism 1 on the bearing surface, allowing the device 2 to reliably move in the first direction as the fixing mechanism 1 is driven by the first movable assembly.

[0079] The driving of the first moving assembly mainly relies on the lifting cylinder 65. The fixed end of the lifting cylinder 65 is connected to the second moving assembly through the fixed plate 62, so that the second moving assembly can drive the first moving assembly as a whole, the fixing mechanism 1 and the device 2 to move in the second direction.

[0080] When the lifting cylinder 65 is in the lifted state, the fixing mechanism 1 and the device 2 can be moved upward so that the fixing mechanism 1 is separated from the clamping cavity 41, so that it can be driven by the second moving component to send the fixing mechanism 1 and the device 2 to the corresponding positions of another adjacent clamping cavity 41; when the lifting cylinder 65 is in the reset and dropped state, the fixing mechanism 1 and the device 2 can be moved downward so that the fixing mechanism 1 enters another adjacent clamping cavity 41, completing the movement of the device 2 along the second direction and the first direction, so that the joints 3 at different positions on the device 2 can be sent to the working position of the screwing mechanism 5 in turn for screwing operation.

[0081] In this embodiment, the number of the lifting cylinders 65 is not limited. For example, in order to maintain better stability, multiple lifting cylinders 65 can be arranged along the second direction between the supporting plate 66 and the fixing plate 62. The design can be flexibly selected based on actual conditions.

[0082] Please refer to Figure 6 、 Figure 7 The second moving assembly includes a moving cylinder 61 provided on the fixed frame 7, and the moving end of the moving cylinder 61 is connected to the fixed plate 62 so that the first moving assembly, the fixing mechanism 1 and the device 2 can be driven to move along the second direction through the fixed plate 62.

[0083] In this embodiment, under the premise of using the moving cylinder 61 , the fixing mechanism 1 can be fixed on the carrying plate 66 or simply placed on the carrying plate 66 .

[0084] In a specific embodiment, the stroke of the movable cylinder 61 can meet the installation requirements of the joints 3 with the longest spacing on the device 2, and the fixing mechanism 1 can be fixed on the supporting plate 66. During the screwing operation, the supporting plate 66 can play a certain supporting role for the fixing mechanism 1. The movable cylinder 61 extends or retracts in one direction, so that the multiple joints 3 on the device 2 can be reliably delivered to the working position of the screwing mechanism 5 for separate screwing operations.

[0085] In another specific embodiment, if the stroke of the moving cylinder 61 is not enough to meet the installation requirements of the connector 3 with the longest spacing on the device 2, the fixing mechanism 1 can be placed on the carrier plate 66. The placement here is not just a simple placement, but a certain positioning, but it is not a clamping relationship, but it can ensure the reliable stability of the fixing mechanism 1 placed on the carrier plate 66. In this case, if the moving cylinder 61 extends and drives the fixing mechanism 1 to move a certain distance in the second direction, and then the lifting cylinder 65 drops and resets so that the fixing mechanism 1 is clamped in the clamping cavity 41, then the fixing mechanism 1 has been supported by the clamping cavity 41, and the moving cylinder 61 can be retracted and drive the first moving component to move a certain distance in the opposite direction, so that the moving cylinder 61 can be reset. If it is necessary to transfer the fixed structure to another clamping cavity 41 again, the moving cylinder 61 can be extended and retracted again. The certain distances of extension and retraction correspond to multiples of the distance between adjacent clamping cavities 41, and the spacing is small. Through this setting, the mobile cylinder 61 can move a small distance, which meets the situation where multiple joints 3 need to be installed on the device 2, resulting in a longer moving distance. There are fewer requirements for the mobile cylinder 61, which reduces the cost of use.

[0086] The fixed frame 7 is provided with at least one guide rail 63. A sliding member 64 or roller is provided on the side of the fixed plate 62 proximal to the guide rail 63. The sliding member 64 or roller is connected to the guide rail 63 to guide the movement of the fixed plate 62 by the movable cylinder 61. The provision of the guide rail 63 ensures that the single travel distance of the movable cylinder 61 is the distance between two adjacent clamping cavities 41, thus ensuring the accuracy of the travel path and the reliability of the sequential installation and tightening of multiple connectors 3. If the guide rail 63 is provided with multiple sections, multiple sections can be provided along a third direction perpendicular to the second and first directions to ensure reliable and stable guidance.

[0087] The arrangement of the sliding member 64 and the rolling member only needs to be able to cooperate with the slide rail for guidance, and there is no excessive restriction on the number and form.

[0088] A guide section is provided on the fixing frame 7 in the area corresponding to the lifting cylinder 65. The distance between the beginning and end of the guide section corresponds to the position of extension and retraction of the movable cylinder 61, and corresponds to a multiple of the distance between two adjacent clamping cavities 41 along the moving direction of the movable cylinder 61. The guide section can provide guidance for the movement and retraction of the movable cylinder 61. In this case, after the movable cylinder 61 extends to drive the fixing mechanism 1 to move to any clamping cavity 41, the fixing mechanism 1 remains stationary, and the movable cylinder 61 retracts to await the next movement of the fixing mechanism 1. This is suitable for the situation where a movable cylinder 61 with a short stroke completes the installation operation of a joint 3 with a long stroke.

[0089] The setting of the guide section can be used to guide the movement of the mobile cylinder 61, specifically a guide groove. The head end and the end end of the guide groove are two limit positions, one corresponding to the position corresponding to the fixed end of the lifting cylinder 65 when the mobile cylinder 61 is in the extended state, and the other corresponding to the position corresponding to the fixed end of the lifting cylinder 65 when the mobile cylinder 61 is in the retracted state.

[0090] The distance between the beginning and the end of the guide section corresponds to a multiple of the spacing between two adjacent clamping cavities 41 along the moving direction of the moving cylinder 61. The multiple depends on the installation order of the connectors 3 on the device 2 and can be one, two or more times.

[0091] The fixed end of the lifting cylinder 65 has a guide post 651 extending from the fixed plate 62 and inserted into the guide section. At least one guide post 651 is provided. Figure 1 、 Figure 7 The guide column 651 can move within the guide section to provide guidance for the moving route of the moving cylinder 61, ensuring that the fixing mechanism 1 can reliably move between the clamping cavities 41 to correspondingly perform reliable installation of the joints 3 at different positions.

[0092] Please refer to Figure 2 The fixing mechanism 1 includes a fixing frame 11, which can form a placement space 12 for the device 2. The outer edge of the fixing frame 11 is provided with a connection hole, and a fastener 14 is provided in the connection hole. The fastener 14 is used to fix or limit the device 2 within the placement space 12. The placement space 12 is used to position the device 2 installed on the fixing frame 11, and the fastener 14 is provided to ensure that the device 2 is reliably installed on the fixing frame 11. Through this arrangement, the reliability of the device 2 on the fixing mechanism 1 can be guaranteed, the accuracy of the device 2 moving with the fixing mechanism 1 to the clamping cavity 41 can be guaranteed, and the deviation of the device 2 can be prevented from affecting the installation effect of the connector 3. The specific fastener 14 can be a screw or a bolt, which is determined in combination with the corresponding hole position or connection position on the device 2.

[0093] Please refer to Figure 2 The fixing mechanism 1 includes a protruding shaft 13 that protrudes from the fixing frame 11 and is arranged away from the placement space 12. The protruding shaft 13 has a first part 131 that is clamped in the clamping cavity 41 and a second part 132 that is located in the moving space 43 and abuts against the side plate 42. The diameter of the first part 131 is smaller than the diameter of the second part 132. The protruding shaft 13 here is the part where the fixing mechanism 1 can be clamped or detached from the clamping cavity 41. The number of protruding shafts 13 can be determined according to actual conditions. For example, multiple ones can be set to ensure reliable support of the fixing mechanism 1 in the clamping cavity 41. The situation of setting multiple ones here refers to the front and back sides, left and right sides of the fixing mechanism 1. The front and back, left and right here are based on Figure 1 The orientation defined by the datum is shown.

[0094] By setting the extended shaft 13 as a stepped shaft body, when the first part 131 is located in the clamping cavity 41, the second part 132 can provide support force by abutting against the side plate 42, thereby preventing the extended shaft 13 from being separated and affecting the reliability of the installation of the connector 3.

[0095] The fixing frame 7 is provided with multiple mounting positions perpendicular to the length of the side panel 42. The side panel 42 can be fixed to any of these mounting positions, allowing the size of the movable space 43 to be adjusted. The length of the side panel 42 is referred to as the second direction, and the direction perpendicular to the length of the side panel 42 is essentially the third direction, perpendicular to the first and second directions. By providing multiple mounting positions, the size of the movable space 43 can be adjusted according to actual needs to accommodate the use of different types of devices 2. Of course, if interference with the screwing mechanism 5 occurs, the screwing mechanism 5 can be moved on the fixing frame 7 to accommodate the use of different types of devices 2, thereby improving applicability.

[0096] Please refer to Figure 1 A universal wheel 8 is provided at the bottom of the fixing frame 7 for changing the position of the automatic joint tightening device. By setting the universal wheel 8, the position of the automatic joint tightening device can be changed according to on-site requirements. If the device 2 is inconvenient to move, this form can be used to achieve it. After moving to a certain position, the universal wheel 8 can be locked, so that the automatic tightening device can be locked in a certain position for operation, thereby improving the applicability of the equipment.

[0097] Several reinforcing ribs are provided on the side of the side panel 42 away from the movable space 43. One end of the reinforcing rib is connected to the side panel 42, and the other end is connected to the fixing frame 7. The provision of the reinforcing ribs can ensure the structural strength of the side panel 42, improve its deformation resistance, ensure the reliability and stability of the clamping cavity 41, and ensure the reliability of the automated tightening installation of multiple joints 3.

[0098] Based on any of the above embodiments, please refer to Figure 4 、 Figure 5 The screwing mechanism 5 includes a sleeve 57, one end of which is connected to a driving component for driving it to contact or disengage from the outer periphery of the joint 3, and the other end of the sleeve 57 is provided with a multi-stage clamping position 571 arranged along its axial direction. The multi-stage clamping position 571 is used to correspond to different driving distances of the driving component and different outer diameters of the joint 3.

[0099] The multi-stage snap-in position 571 of the sleeve 57 can correspond to connectors 3 of various outer diameters. By screwing the snap-in position 571 corresponding to the outer diameter of the connector 3 into contact with the connector 3, the specific type of connector 3 can be tightened in a targeted manner, thereby ensuring the reliability of the installation of the connector 3.

[0100] The driving component can drive any engaging position 571 of the sleeve 57 to contact or disengage from the connector 3. Specifically, the driving component can drive the sleeve 57 to move to contact the connector 3, and then the connector 3 of the corresponding outer diameter size can be reliably screwed onto the device 2 by rotating the sleeve 57; after screwing, the driving component drives the sleeve 57 to move to disengage from the connector 3.

[0101] Different driving distances of the driving component can be controlled based on the control element, specifically, corresponding driving programs can be set based on connectors 3 of different outer diameters to achieve automated tightening of the connector 3 .

[0102] In this embodiment, the sleeve 57 is directly processed so that connectors 3 of various sizes can be installed on the same sleeve 57 without replacing the sleeve 57 , which makes the operation more convenient and more applicable.

[0103] Based on any of the above embodiments, please refer to Figure 4 The driving component includes a first driving member 51 and a second driving member 52. The first driving member 51 is connected to the fixed frame 7 via a connecting frame 53. The second driving member 52 is connected to the first driving member 51 via a connecting plate 58 to achieve movement. The second driving member 52 is connected to the sleeve 57 to achieve rotation of the sleeve 57. The movement of the second driving member 52 is the movement of the sleeve 57 toward or away from the joint 3. The rotation of the sleeve 57 driven by the second driving member 52 is the rotation to tighten the joint 3 on the device 2.

[0104] The driving component also includes a guide member, which is rotatably connected to the sleeve 57 to achieve rotational guidance; the guide member here can specifically be in the form of a turntable, a disc, a bearing 55, etc., which can provide guidance when the second driving member 52 drives the sleeve 57 to rotate, ensuring that the rotation path of the sleeve 57 is reliable and accurate, and ensuring that the joint 3 can be reliably tightened.

[0105] Alternatively, the guide member may be slidably arranged relative to the second driving member 52 to achieve translational guidance when the second driving member 52 moves, thereby ensuring the accuracy of the route of the sleeve 57 moving toward or away from the joint.

[0106] Based on any of the above embodiments, please refer to Figure 4 The second driving member 52 is a driving motor connected to the first driving member 51 via a guide plate 56. The output end of the driving motor is connected to the sleeve 57 via a coupling 54. The driving motor is connected to the sleeve 57 via the coupling 54 so that the sleeve 57 can be driven by the driving motor to rotate. The rotation here can be bidirectional, which is suitable for tightening or loosening the joint 3.

[0107] At least one guide plate 56 is provided along the axial direction of the sleeve 57. A guide hole is provided in the guide plate 56. A guide member is provided in the guide hole. The guide member and the sleeve 57 are connected to one end of the coupling 54 for rotation. The guide member is preferably a bearing 55. The sleeve 57 is connected to one end of the coupling 54. Figure 5 The figure shows the shaft structure. Multiple guide plates 56 can be set. A bearing 55 can be nested in each guide plate 56 so that it can contact the shaft structure from multiple axial directions to guide the rotation of the sleeve 57 and ensure the accurate and reliable rotation of the sleeve 57.

[0108] Based on any of the above embodiments, a control mechanism is further included. The fixing mechanism 1 is provided with a scanning bar or a radio frequency card. The control mechanism is used to determine the type of the device 2 based on the information of the scanning bar or the radio frequency card so as to control the operation of the driving component and the moving mechanism 6.

[0109] By binding the barcode or radio frequency card with the supporting program of the control mechanism, the control mechanism scans the scanning bar or radio frequency card on the fixing mechanism 1 when in use, which can start the corresponding device connector installation program, thereby improving the intelligent automation level of device connector installation.

[0110] In this embodiment, it should be noted that the scanning bar and the radio frequency card are arranged on the fixing mechanism 1, and each fixing mechanism 1 corresponds to a different device 2. By equipping multiple sets of fixing mechanisms 1, the connector 3 of different types of devices 2 can be installed to improve the overall applicability of the equipment.

Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
